RemoteApp: user can’t reconnect
When using RemoteApp you can’t ‘just’ disconnect/reconnect.
You need to do a proper logoff.
However you can force your users to logoff instead of disconnecting this way:
– go in the RDPlus AdminTool,
– go to the ‘Server’ tile,
– then go into ‘Group Policies’ and check ‘All disconnected sessions will be immediately terminated’.
